Unlike the diesel additive 1: 400 of the ERC can be measured a consumption-lowering effect here. For an accurate indication it's a little early, but it is my 2.5 liter TDCI in the range 0.2 to 0.5 liters of diesel per 100km!
Thus, it corresponds to my previous favorites (Super diesel additive of LiquiMoly) the price is only 1/4 and the bottle is exemplary with liquid end, as I was used from gasoline additives it.
So it was clear that this product is one in my pantry immediately. The biocide contained can also be adapted to the unfortunately biodiesel containing (new) Fuel suspect.
In the meantime we have the addition in an old (> 20 years> 120.000) tested Mercedes Hymer. Simultaneously 150ml 2T oil per tankful because this combination has been shown to me to be very positive. In winter, I give the ERC for the last 25.000km even up to 300ml 2-stroke oil to. Nevertheless, you also have no 2-stroke oil a noticeable improvement by ERC 1: 1000.
